A comprehensive geospatial database of nearly 100,000 reservoirs in China

Data componentsFolder “CRD v1.1” contains the recorded (5,143) reservoirs from yearbook and document data and all (97,435) reservoirs from CRD v1.1 (China Reservoir Database) two parts:• CRD_v11_all_reservoirs (in both shapefile format and the comma-separated values (csv) format): This database catalogs the location information of 97,435 reservoirs in China, with an aggregated area of 50,085.21 km2 and an estimated total storage capacity of 979.62 Gt. The attributes of all the CRD reservoirs (in all cases) include location information (province, prefecture, and county), inundation area, and estimated storage capacity, river order, discharge, and residence time of reservoirs.• CRD_v11_record_reservoirs (in both shapefile and csv): The 5,143 reservoirs in the CRD database were directly derived from the yearbook and other documents data, accounting for 59% and 82% of the total reservoir area and storage capacity of the CRD database, respectively. This reservoir information was mainly obtained through manual compilation. The attributes of the recorded reservoirs include name, province, prefecture, and county where the reservoir is located, water area, normal water level, storage capacity, reservoir class, main use, and regulation type.

"CRD v1.1"数据集文件夹包含两部分数据：其一为源自年鉴与文献资料的5143座已收录水库，其二为中国水库数据库（China Reservoir Database，CRD v1.1）中的全部97435座水库。
• CRD_v11_all_reservoirs（格式为shapefile与逗号分隔值（comma-separated values，CSV））：该数据库收录了中国97435座水库的位置信息，总淹没面积达50085.21平方千米，估算总库容为979.62吉吨（Gt）。所有CRD水库的属性字段均包含位置信息（省、地级市、县级行政区）、淹没面积、估算库容、河流等级、径流量以及水库驻留时间。
• CRD_v11_record_reservoirs（格式为shapefile与CSV）：该数据库中的5143座水库直接源自年鉴及其他文献资料，分别占CRD数据库总水库面积与总库容的59%与82%。此类水库信息主要通过人工整编获取，其属性字段包含水库名称、所在省、地级市、县级行政区、水域面积、正常水位、库容、水库等级、主要用途以及调度类型。
